POWDER AND PARTICLE PROCESSING – Applications – Plastics – Recycling Recycling of plastic film with granulators supplied by HOSOKAWA ALPINE From film feeding systems to film flake silos – we are your single-source partner. Specially optimised to recycle plastic film, our Rotoplex® film granulators are particularly reliable and cost-effective in operation, regardless of whether the feed product is film edge trims, cast film, film waste, reel scrap or finished film. ALPINE has a vast fund of practical experience for in-line and off-line modes of operation and supplies not only stand-alone machines but also complete processing systems including fluff transport units, silos and reclaim extruders. Film comminution with ALPINE granulators The values in the table are reference values. Lower or high throughput rates are possible dependent on the material being processed and the machine design.
